Abstract

GONZALES CAMARENA, David Enmanuele; JAULIS SOLORZANO, John Fortunato; TAPIA EGOAVIL, Elena Zoraida  and  SAMALVIDES CUBA, Frine. Antibiotic sensitivity of bacteria causing urinary tract infections in a public hospital from January until June, 2008. Rev Med Hered [online]. 2009, vol.20, n.1, pp.11-15. ISSN 1018-130X.

Objective: To describe the antibiotic sensitivity of positive urine cultures performed in the Hospital Nacional Cayetano Heredia, from January until June, 2008. Material and methods: Descriptive and retrospective case series was performed. We revised the urine positive cultures from January until June, 2008. Results: From a total of 1253 positive urine cultures taken from non-hospitalized patients (1049 cases) the following was isolated: Escherichia coli 76% followed by Klebsiella spp. 5% and Citrobacter sp. 3%. Escherichia coli were found sensitive to amikacina, nitrofurantoína, ceftriaxona and ciprofloxacin in 93.5%, 88%, 78% and 44.59% respectively. In hospitalized patients (204 cases), the prevalence was 49.01% for Escherichia coli followed by 11.39% for Enterococcus spp. and 8.42%. for Klebsiella spp. Escherichia coli was found sensitive to amikacina (88.89%), nitrofurantoína (75.26%), ceftriaxona (42.88%) and ciprofloxacin (26.04%). Nitrofurantoin showed low resistance in hospitalized patients (16.49%), as in for non-hospitalized patients (6.48%) Escherichia coli. Conclusions: Amikacin is a good option for empiric treatment. We also found a high resistance percentage in strains isolated with the most common used antibiotics. Nevertheless, less used antibiotics as Nitrofurantoin have a higher sensitivity percentage against Escherichia coli.(Rev Med Hered 2009;20:11-15).
